Summary
The Starlink-1055 satellite, also known as Starlink 1055 and designated as OBJECT_ID 2019-074AZ, was launched on November 11, 2019, from the Cape Canaveral Air Force Station's Launch Complex 40 using a Falcon 9 launch vehicle. Manufactured by SpaceX (SPXS), this satellite has a dry mass of 248 kilograms and a launch mass of 260 kilograms. Its dimensions are a length of 0.2 meters, diameter of 2.8 meters, and span of 9 meters with a box plus pan shape. Equipped with Ku/Ka-band payload (all) and optical inter-satellite links (on a few prototypes), it uses solar arrays and batteries for power generation and krypton ion thrusters for propulsion. The satellite's mission is focused on communication purposes as part of the Starlink V1.0-L1-48 constellation.
Starlink is a satellite constellation developed by SpaceX with the aim of providing global broadband internet coverage. Thousands of small satellites are deployed in low Earth orbit (LEO), enabling high-speed internet access even in remote areas. However, the rapid increase in satellites raises concerns about space debris and the potential for collisions, which can lead to further debris creation and endanger other spacecraft. Additionally, the sheer number of Starlink satellites can affect astronomical observations by increasing light pollution. Proper deorbiting plans and international coordination are essential to mitigate these challenges and ensure long-term sustainability in space.
